Why can't I open or read my email in firefox. This problem started last week, and now I have to use internet explorer to read my emails.

On Oct. 28th problem started when I went to email preview page and could not open or read any emails. I have been using Firefox browser for several years and never had this problem before the above date. If I want to read emails, I have to use Internet Explorer now.

You may have zoomed the page by accident with Ctrl and the mouse scroll wheel.
Reset the page zoom on pages that cause problems.

Why am I unable to access my new Post Office Account they state that you will not allow and I will have to use Internet Explorer why?

I have just opened a new account with the Post Office but I am unable to access this on the net. Telephoned Customer Services but say that I will not be able to access through Firefox and will have to use Internet Explorer. Going back to Internet Explorer is not something I want to do because I like Firefox, please explain why Firefox is blocking access if this is true. I have clicked 'allow' but it made no difference and the only message coming up is "timed-out" when I have been much less than 5 mins putting security details. Please advise. Paula

I doubt if Firefox is blocking access. More than likely, that website is made to use ActiveX, or other proprietary Microsoft code, that only Internet Explorer can handle.
If you post the address of that "Post Office" website, maybe one of us support helpers can figure out the exact reason for that.

I can open my hotmail email but cannot reply or send new messages. this just started last week.

I can open my hotmail email but cannot reply or send new messages. this just started last week. Don't know why not. Is this a Firefox issue or a Microsoft issue? 'Cause it's near impossible to get Microsoft to get back to me. Hope you can help me.

I resolved both my problems. The problems with Walgreens is that my own Frontier internet connection is very slow and will allow only minimal downloads. When I used a Verizon Hot Spot to download pictures they downloaded without any problem. So I am working iwth Frontier to resolve my slow internet speed. The problem with pictures be syncronized to a gallery was resolved by using the Help column and the pictures were easily deleted by following their instructions.

Why can´t I take a step back with the keyboard shortcut, cmd + ö, it was possible before, now you have to go to the bar at the top and "go back one step." I have Mac-systems, I also have mouse elbow, and do not want to use the mouse too often.

This article lists some other options for "Back" navigation. Do any of them work for you?

I want to use Firefox and my husband wants to use internet explorer. Can we do that?

'''vista'''We have always used Internet Explorer as our browser but lately, some of my links will not open. I want to install Firefox because that is what we use at work and my sites open there. Can we continueu to use both?

Yes you can. You can even have Firefox and IE running at the same time.

I was able to use the findmyiphone app last week, but now I have been getting an error message "Can't load findmyiphone. There was a problem loading the application." please help as we are trying to locate an ipod with pics of a no deceased loved one.

Had the same problem and the same message -- was suddenly unable to access icloud apps on my pc, also using Windows 7 and Internet Explorer. After several days of pulling my hair out, decided to try a different browser and was able to get in by using Firefox instead of Internet Explorer. Hope this helps.

Firefox icon disappeared, have to use Internet Explorer to access web sites. Although I can get into Yahoo home page, am unable to open e-mail account.

Turned on computer this am and firefox icon not there. Used Internet Explorer to access web sites. Was able to access my Yahoo home page but not able to open my e-mail account. I am not savvy enough to change settings by myself, so I really need help.
Thank you

Hi--I tried your suggestion and no dice. A window came up with the following:The item 'Firefox.exe' that has this shortcut will no longer work properly. Do you want to delete?
Another window said 'C:Program files (x86) Mozilla Firefox\firefox.exe' specified in the target box is not valid. Make sure the path and file name are correct.
I have no clue as to what that means. I did delete the shortcut.
Finally went into our Kaspersky virus protection and found Firefox is in quarantine and that is probably why I am unable to uninstall and reinstall.
Any ideas????
Thanks, Ginny

Why can't I open Slideshow in Yahoo mail in Firefox 15.0.1 when it works fine if I use Safari? Mac OS X / v10.7.5

For the last two days I've had a problem opening attached photos in the Yahoo Mail Slideshow feature. The screen goes to a grey layer as usual, but the photo never opens to view it. I don't think it's a Yahoo problem as the Slideshow works fine if I access my mail using Safari.
Some older posts suggested clearing the cache of personal cookies, but I don't store any history on this computer so there is no cache to clear.

Thank you.
I've restarted Firefox in Safe Mode as suggested and when I open the Yahoo Mail slideshow it works fine. I guess that tells me there may be a corrupted file somewhere. I'm just not sure how to go about finding out how to correct it. When I try to switch to the 'Default Appearance Theme' it won't allow me to do it while in Safe Mode. Should I be trying this AFTER I get back out of 'Safe'?
I don't keep any cache so I'm not sure how I can bypass it. I've tried reloading the mail inbox page by pressing "Command + Shift + R" but to no avail...
This problem just came up in the last two days, so I went back one week in my Time Capsule backup to reload a copy of Firefox from a time when I wasn't having problems - still no luck. The photos won't open in the slideshow preview on Firefox unless I'm running in Safe Mode.
Thank you in advance for any suggestions as to how to isolate the file or add-on that may be corrupted...

Why can't i open pop up's i asked firefox to allow the popup and even went in and turned off pop up blocker but it still fails to let me see what i'm going for

i need to see an item in the walker exhaust website . and when i click on the picture to have it go larger i get the drop down across the top that said popup blocked. i went in and asked for the popup and nothing. i then went in and turned it off and closed the option page and tried again and nothing still will not allow it. i have had this problem before and getting tired of it. i almost would rather close the popup's than to not get the ones i need to see.

Hello,
'''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
''(If you're not using it, switch to the Default theme.)''
* You can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
''Once you get the pop-up, just select "'Start in Safe Mode"''
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
''When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.''
Thank you.

Why can't I open links in a new tab with a right click anymore? And why has the toolbar removed the refresh button?

Several basic functions seem to be have vanished from Firefox. I can no longer open links in new tabs with a right click, and the refresh browser button (and back/forward navigation buttons, etc) do not appear in with consistency anymore. How do I get these basic navigational tools back? (most recent updates are installed)
== This happened ==
Not sure how often
== 7 July 2010

* Make sure that you have the "Navigation Toolbar" and the "Bookmarks Toolbar" visible: "View > Toolbars"
* If items are missing then see if you can find them in the "View > Toolbars > Customize" window
* If you see the item in the Customize window then drag it back from the Customize window to one of the toolbars.
* If, in "View > Toolbars > Customize", you do not see that item then click the "Restore Default Set" button

Opened up Firefox this morning and can't open a single website....have to use Internet Explorer (oh the shame). I tried reinstalling firefox and restarting my computer. Don't know what else to do or why I can't get any internet on Firefox.

Unable to connect
Firefox can't establish a connection to the server at www.facebook.com.
The site could be temporarily unavailable or too busy. Try again in a few
moments.
If you are unable to load any pages, check your computer's network
connection.
If your computer or network is protected by a firewall or proxy, make sure
that Firefox is permitted to access the Web.

It is always a good idea to back up your bookmarks, if you are able to do that now it may help, and if you are considering using them in an alternative browser it may be a good idea to back them up as HTML as well as the default .json files.
* see [[Backing up and restoring bookmarks]]
Have you read the articles shown in my first message above with the blue clickable links. One of the first things to try is using Firefox in firefox [[safe mode]] which should be available from your program list, BUT when trying that on the first dialogue do not make changes just click on continue.
*Does that work ?
* did you see the list of options and click on the continue button ?
* are you seeing any error messages ?

HT1338 why can't i open itunes, it keeps telling me i need mac os x & that is what i have

can anyone help me i haven't been able to open my itunes at all

What is the iTunes version you are having, and what is the MacOS X version?
Both versions need to match - iTunes 11.1 needs MacOS X version 10.6.8 or later. Is your profle signature Mac OS X (10.4.10) correct?

I cleaned my computer and some programs were deleted. Now I can't open my Hot Mail. I have to use Internet Explorer. Facebook was affected, too, but I uninst

I uninstalled Firfox and after I reinstalled the program Facebook works. I can use hotmail thru Internet Explorer but I wouild rather have Firefox work.

Clear the cache and the cookies from sites that cause problems.
"Clear the Cache":
*Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"
"Remove Cookies" from sites causing problems:
*Firefox/Tools > Options > Privacy > Cookies: "Show Cookies"
Start Firefox in [[Safe Mode|Safe Mode]] to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
*Do NOT click the Reset button on the Safe mode start window or otherwise make changes.
*https://support.mozilla.org/kb/Safe+Mode

You may need to reinstall Firefox if files in the Firefox program folder were affected.
Download a fresh Firefox copy and save the file to the desktop.
*Firefox 20.0.x: http://www.mozilla.org/en-US/firefox/all.html
Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.
*Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you will also lose your personal data like bookmarks and passwords from profiles of other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
*It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
*http://kb.mozillazine.org/Uninstalling_Firefox
Your bookmarks and other profile data are stored in the Firefox Profile Folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.
If you keep having problems then also create a new profile.

I have been using Internet Explorer and have now downloaded Firefox but cannot find my imported favourites. Where can I find them?

I have now downloaded Firefox as my default browser and when downloading I asked for my favourites from Internet Explorer to be exported to Firefox. I cannot find anywhere on the Firefox site that allows me to open my favourites. Can you please advise.

As a Test:
Hold down the option (or alt) key and launch iPhoto. From the resulting menu select 'Create Library'
Import a few pics into this new, blank library. Is the Problem repeated there?

Why can't I open or read my email in firefox. This problem started last week, and now I have to use internet explorer to read my emails.
